Question

de scris masa pentru:
HCE, HB2, NH3, NO, NO2, N2O3, N2O5.

Answer 1

Masa molara NH₃=1*14+3*1=14+3=17
Masa molara NO=1*14+1*16=30
Masa molara NO₂=1*14+2*16=46
Masa molara N₂O₃=2*14+3*16=76
Masa molara N₂O₅=2*14+5*16=104

Answer 2

Masa molara a NH3=N+3*H=14+3*1=14+3=17 g/mol
Masa molara a NO=N+O=14+16=30 g/mol
Masa molara a NO2=N+2*O=14+2*16=14+32=46 g/mol
Masa molara a N203=2*N+3*O=2*14+3*16=28+48= 76 g/mol
Masa molara a N205=2*N+5*O=2*14+5*16=28+80=108 g/mol
